Precautions
1. Each valve is fixed on the manifold with
two M4 mounting screws. Please
tighten the screws properly when
valves are reassembled.
Screw tightening torque: 1.4 N·m
2. When using 6 or more stations on the
manifold, supply pressure from both
sides of P port.
In the case of common exhaust type,
exhaust air from both sides of R port as
well.
Construction/Dimensions
1. This valve has a breathing port for the main valve at the bottom. To prevent
malfunctions, do not clog the breathing port.
(When mounted on a metal surface, breathing air can go through from the breathing
port to the breathing groove; however, when the valve is mounted on a rubber surface,
the breathing air may be blocked by the deformation of rubber.)
2. Take measures to prevent ingress of dust and foreign matter from the exhaust port and
other unused ports. Also, take measures to prevent ingress of water and foreign matter
from the breathing port of the diaphragm.

Specifications
Note) Impact resistance: No malfunction from test using drop impact tester, to axis and right
angle directions of main valve, each one time when pilot signal ON
and OFF. (Value in the initial stage)
Vibration resistance: No malfunction occurs on the test with one sweep from 45 to 1000
Hz, to axis and right angle directions of main valve each time when
energized and de-energized. (Value in the initial stage)
